Format: Paperback
This is a wonderful, clearly-written student textbook that examines a number of pre-computer cipher systems (substitution, transposition, Playfair, Enigma, etc), including a few that are rarely covered by other cryptography books (such as the Hagelin/M-209 and Lorenz cipher machines). The book looks at the systems principally from a mathematical and cryptanalytic viewpoint and each chapter contains a number of examples and exercises. The last chapter covers modern systems (namely DES and RSA). I recommend this book highly.

5.0 out of 5 stars well written and for all 7 Aug. 2004
By r bilinski - Published on
Format: Paperback
This is not a schoolbook, yet it takes from the format some usefull features for such a book : you have some worked out examples and a few exercises to practice. After all, math is not something you read like a novel, but rather something you DO! The author understands that.
But the book also has an easy going feel to it and is very clear. Mixed in with the math, you have tidbits of history and general culture mixed in. If you compare it to a very good book out there (the code book by Singh), you find out more about the codes and the mechanics of them in this book.
good read!

4.0 out of 5 stars Survey of Ciphers 19 Jan. 2007
By Kimball O'Hara - Published on
Format: Paperback
It's a good book if you have an interest in ciphers and haven't read much on the subject. It's not a book on modern cryptography and covers very little in the way of recent breakthrough technology. Based on your level of interest and experience it might or might not be the right book for you. It gets four stars from me because the author presents clear, well researched information.
